Overview
The AS4PMHM3/86A is a standard recovery rectifier from Vishay Semiconductors, featuring a 1 kV repetitive peak reverse voltage and a 4 A average forward current rating. It utilizes the eSMP series TO-277A-3 (SMPC) surface-mount package. Key electrical parameters include a maximum forward voltage of 920 mV at 4 A, a reverse leakage current of 350 nA, and a typical reverse recovery time of 1.8 µs. The device supports a maximum surge current of 100 A and operates within a junction temperature range of -55°C to +175°C.
Feature Summary
- Features oxide planar chip junction technology for robust performance.
- Designed with low profile characteristics suitable for automated placement.
- Complies with RoHS directives and WEEE regulations.
- Halogen-free construction according to IEC 61249-2-21 definitions.
Applications
- High frequency power supply circuits
- Automotive electronics systems
- General purpose rectification in surface mount assemblies
Procurement Notes
Verify the specific suffix against official datasheets to confirm exact packaging and qualification status. Ensure compatibility with existing PCB footprints for the TO-277A-3 package. Confirm that the component meets all required environmental standards for the target application before finalizing procurement orders.
Selection Notes
Select this component when high voltage isolation and moderate current handling are required in a compact surface-mount form factor. The standard recovery speed makes it suitable for lower frequency applications compared to ultrafast alternatives. Consider the thermal management requirements associated with the SMPC package for high-power density designs.
Part Context
This part belongs to the AS4P series of rectifiers manufactured by Vishay Semiconductors. The series is characterized by its use in general-purpose rectification tasks where reliability and compliance with automotive standards are prioritized. The eSMP branding indicates specific manufacturing processes aimed at enhancing performance and consistency.
Replacement Considerations
Direct substitutes may include other Vishay parts within the AS4P family or equivalent components from other manufacturers offering similar 4A/1000V specifications in the TO-277A package. Verify pinout compatibility and electrical parameter margins before substitution.
